nmcnmn son m'nnve, sconnnve AND WASHING WOOL AND err-ma rrnnous T T MATERIALS T T Application filed September 16, 1926, Serial No. 135,900, and in Great Britain September 21, 1925.

T *6 are placed ina movable vessel, hinged or ypivotedat its upperedge, so as topermit of the vessel being tilted for a sicle-tip discharge under the control of gearing. Hitherto, said machines or apparatus have comprised an inner movable hinged vessel and an external vesselpr vat as in our prior British specifications Nos. 101,060; 108,809; 142,602 and 17 8,940, the inner vessel or cage being hinged to the side of the outer vessel or vat to permit of the cagebeing swung upwardly clear of the vat. Thepresent invention has for its chiefobject to simplify and cheapenthe construction; of such dyeing machines or apparatus whereby they may be used either for single or two bath dyeing.

According to the present invention one of the vessels is dispensed withand the remaining vessel adaptedto be hinged or pivoted along itsupper edge in a frameor bracket and shown lnjFlgure 3, Figure 6 1s a similar view serve as the dyeing vessel. In an embodiment ofthe invention the hinged or pivoted vat or vessel islined with or constructed of any appropriate material and hasaperforated false bottomaifording between it and thebottom proper, a space or chamber for circulating the steam liquor or its equivalent through the machine. a The hinging or pivoting of the vessel is effected in any appropriate manneneither by mounting the vessel on its upper edges to the adjacent frame or structure and means are provided-such as screw, chain, rope or other similar gearing foreither tilting the machine automatically or otherwise by appropriate mechanism, for ,emptyingor discharging the contents, as and Also the connections to the circulating space at the bottom of the vessel'will be such as to allow of the necessary tilting or turning ployed in Figure 4:.

hingesor pivots at suitable points at one of movement being given to thevessel withor without disconnecting the connections as is found advantageous.

In order that the invention may be clearly understood and readily carried into effect, the same will now be more fully described with reference to the accompanying drawings in which:-\

Figure 1 is a longitudinal or frontsectional view of adyeing machine according to the invention, the mechanism for tipping the vat not being shown. T

Figure 2 is an end view showing the dyeing vat in two positions,the full line position indicating the normal position of the vat and the dotted line position that which it assumes the pump and pipe connections not being T shown.

Figures 3 and 4 show alternative methods Oftilting the vat, by double and single screw lifting gear respectively. i

Figure 5 is a front View of the gearing in part of the single screw lifting gear em- Figures 7 and 8 illustrate in front andside elevation, respectively, a slightly modified form of the invention.

Referring now to the drawings in which it will be notedin Figure lthat the mechanism for tipping the vat is not shown, and in Figure 2 the mechanism for tippingthe vat and the pump and pipe connections are not shown inorder to better illustrate the other structuraa indicates the vat whichis of i the fulcrums may take the form of short stub axles or trunnions engaging lugs or brackets d on the vat a, as shown in Figure 7.

Steam for heating purposes is uniformly delivered beneath and through the false bottom e (see Fig. 1), by way of a main perforated steam pipe 7 extending along the base of the vat and heated air may be uniformly delivered, for agitation of the material as and when required, by way of the pipe f in conjunction'with a branch pipe The pipe f may also be fitted with small branch inlet pipe f (Fig. 7), whereby the dye may be introduced Into "the machine along with the steam supply, a more uniform distribution ofth'e dye being thereby obtained.

Particular attention is called to the fact that the single delivery pipe f carries steam for heating purposes, air for the agitation of the material, and also the dye. The air is introduced into the pipe 7 by means of a branch pipe f, and the dye is introduced into pipe f by means of the branch pipe f Circulation of the liquor within the vat is controlled by means of a pump g, automatic sealing joints being provided at it, i, permitting the uptake pipes j, k, respectively, to be instantly and automatically disconnected or connected as the vat a is raised or lowered.

As shown in Figure 1, the pipe y', communicate with the vat, respectively, below the false bottom e and above the same, so that when the pump 9 is operating, the liquid in the vat will e continuously circulated through such false bottom and the material in the vat. The joints h, 2', permit the vat to be bodily moved, as described relative to the pump g.

As shown, thevat a is preferably formed with curved sides to facilitate the side tipping discharge movement. To effect this side tippinga power-driven shaft Z, see Figures 3 to 6, is mounted horizontally and longitudinally behind the vat a at or about the floor level, with screw shaft m carried by trunnion bearings no associated with said shaft Z. The other extremities of said screw shafts are pivotally connected one on each side ofthe vat a at a point. below the horizontal center line of the vat to permit, when the screw shafts m are rotated, of the vat being raised. or lowered, see Figure 4. The connecting gear 0, between the screw shafts and the power shaft is of the bevel planet type, whilst each shaft being carried by the trunnion bearings n permits of the necessary angular movement of the vat, a. An ordinary multiplying gear for the dr r n e he pewer h ft, and a direct reversing gear may be provided both referablycqntrolled from a single driving elt.

InEigures 3 and5, the primary solid screw shaft-s m, are reduced inlength and fitted with a w da he ew ext r all threaded screw, shaft p. slidable thereon, the hollow seremba n a ng aa eas wd nal k y 9 r in the solid screw shaft m. The latter is in threaded engagement with a non-rotating nut 1" which rotatably supports the hollow screw shaft 30 and the hollow screw shaft 1) is in threaded engagement with the non-rotating swivel attached to vat a nut 8. The nut z is prevented from rotating by any convenient means, as for example by a side extension I? thereon engaging slidahly on a guide rod u. As the solid screw shaft m is rotated its nonrotating nut 1' is raised or lowered and thereby raises or lowers the hollow screw-shaft p and its connections to the vat a. At the same time the rotation of the solid screwshaft m is transmitted by the pin and keyway device to the screw shaft p which operating through the stationary nut 8 further raises or lowers the vat a. As shown in Figure 4, however, lifting single screws m are employed although the double screw arrangement avoids of havin screws of undue length.

IVhile preferring the above described methods for raising and lowering the vat from one position to another it will be understood that any other appropriate means may be utilized. Also the pipe connections will in all cases be such as to," permit of swinging or tilting movements of thef'vat, as and when required.

Alternatively the lifting gear may in some cases comprise chains w, disposed at each end of the machine and passing over runners :2, supported by end framesc and a reversing mechanism g, may also be provided.
